Set/reset latch

WebThe S-R Latch is one bit of memory Set is “true” -> stores 1 Reset is “true” -> stores 0 Study Notes We’ve been talking bits, bytes, 1s, 0s…but how does a computer actually retain memory? It retains memory one bit at a time, using an S-R Latch. Imagine we have the gate circuit shown below. Let’s look at what is going on. We have: Two switches. Simple set-reset latches. When using static gates as building blocks, the most fundamental latch is the simple SR latch, where S and R stand for set and reset. It can be constructed from a pair of cross-coupled NOR or NAND logic gates. The stored bit is present on the output marked Q. SR NOR latch See more In electronics, flip-flops and latches are circuits that have two stable states that can store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs … See more Transparent or asynchronous latches can be built around a single pair of cross-coupled inverting elements: vacuum tubes, bipolar transistors, field effect transistors, inverters, and inverting logic gates have all been used in practical circuits. Clocked flip-flops … See more Timing parameters The input must be held steady in a period around the rising edge of the clock known as the aperture. … See more • Latching relay • Positive feedback • Pulse transition detector See more The first electronic latch was invented in 1918 by the British physicists William Eccles and F. W. Jordan. It was initially called the … See more Flip-flops and latches can be divided into common types: the SR ("set-reset"), D ("data" or "delay" ), T ("toggle"), and JK. The behavior of a particular type can be described by what is termed the characteristic equation, which derives the "next" (i.e., after the … See more Flip-flops can be generalized in at least two ways: by making them 1-of-N instead of 1-of-2, and by adapting them to logic with more than two states. In the special cases of 1-of-3 encoding, or multi-valued ternary logic, such an element may be referred to as a flip … See more
